What kind of gains from N/A motor?

Is CHP Canadian Horsepower? HA! Before you correct me, I know what it means. It's just funny, Canadian!

You think it's a good idea to mess with the maf design? I think you'd need some major air consumption before the stock maf would become restrictive.

Absolutely, the stock MAF is good for 250 or so HP, but that is a reflection of it's sensitivity. It can flow enough air for twice that much power. At 500 HP, you MIGHT see a significant restriction. But you will never hit it, since it is NA and you would run out of fuel.
